SPECIFICATION forming part of Letters Patent No. 786,735, dated April 4, 1905.

Application led July 24, 1903. Renewed September 13, 1904:. Serial No. 224,323.

To all toi/1,077?, it' may concern:

Be it known that I, CHRISTIAN Donn, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Bottle-Stoppers, of whicli the following is a specification.

My invention consists or' certain improvements in the bottle-stopper for which I have obtained Letters Patent of the United States numbered 715,765, dated Decemberl, 1902, the objects of my present invention being' to permit of the making of such parts of the stopper as are composed of glass by simple and easy pressing operations and to prevent tampering with the stopper by so constructing a part of the same that it will be injured or destroyed it' such tampering is attempted.

In'theaccompanying drawings, Figure 1 is a sectional View ot' the upper portion of a bottle with stopper therefor vconstructed in accordance with my invention, and Fig. 2 is a side view of one of the elements of the stopper.

'Ihe neck of the bottle has a swelled portion 1 and a cylindrical portion 2 abovethe same, and at the base of the neck is seated the lower member 3 of my improved stopper, which consists of a plug having a central opening 4c and 'an external packing-lung 5, of cork or other material, which will engage with the base of the bottle-neck, form a tight joint ception of theilanged lower end of the second or intermediate member 7 of the stopper, which consists of a block having a central recess 8 lor the reception of the valve 6, lateral slots 9, extending through the block inline with this recess, and notches 10, formed in the upper corner of the block and extending inwardlybeyond an Aannular groove which is .formed in the upper portion ofv said block 7 and receives the lower portion of the upper or third member 11 of the fastening', the latter member consisting` of a tube which is adapted tothe upper cylindrical portion 2 of the bottle-neck and has an external sealingring 12, adapted to an internal groove in said cylindrical portion 2 of the neck.

The diameter of the central opening' 8 in the lower portion of the block 7 of the stopper is but slightly greater than the diameter of the valve 6. Hence they latter has no movement other than vertical movement in said opening. Consequently when the bottle is held in an upright position the valve must neces-v sarily seat itself upon the upper end of the block 3 and close the opening I in said block. Vhen the bottle is tilted, however, the valve is free to move in the central opening of the block 7 sufliciently to permit flow or' liquid through the opening 4 and thence through the slots 9 of the block 7 into the expanded portion 1 of the neck and Jfrom the latte-1', through the notches 10, into the tube 11 and thence out of the mouth or' the bottle. By forming the central block 7 with a lower Vopening and lateral slots and simplynotching the upper corners of said block the latter can be readily made from glass by a simple andl easily-performed pressing operation.

, The slots 9 are olfset 1n respect tothe notches 10, as shown in Flg. 2, so that a wire 'or other implement cannot be passed through valve-seat', a valve, a block superposed on the i seat and having notched upper corners and bottom valvereceiving chamber with lateral slots offset in respect to the notches, and means Jfor retaining said block in .position uponI the valve-seat, substantially as specified.
